called "garbage Collector", as the name implies is the garbage collector, then only the object called garbage can be recycled by GC. That is, the memory used by a reference type object needs to be reclaimed by GC and needs to be garbage first. So. NET how to determine a reference type object is garbage,. NET's judgment is simple, as long as the object or its contained sub-object is determined that no reference is valid, then the system considers it to be garbage.With these two basic concepts in
[Switch] the difference between using managed and unmanaged resources in C # And how to manually release unmanaged resources :,
Managed resources refer to. NET resources that can be automatically recycled, mainly the memory resources allocated on the
heap, then I have to be responsible for cleaning up this object:
foo* PF = new Foo (2);
//...
Delete PF;
The C + + compiler actually uses two heaps, a managed heap, and an unmanaged heap, and then allocates different memory by overloading the new operator to create instances of different types of classes.If I create a bar instance inside the heap, I can ignore it. When no other code

overloading the new operator to create instances of different types of classes. If I create a bar instance inside the heap, I can ignore it. When no other code is using it, the garbage collector automatically cleans up the class and frees up the resources it consumes. There are constraints on managed types: they cannot implement multiple inheritance, or are inherited versus
only options left are managed switches and unmanaged switches. A managed switch is better, and of course its price is more expensive than a unmanaged switch.

You can also expand yourself to your own needs. If you are interested, you can refer to MSDN.2.
